Prebiotics are a type of fibre found in vegetables, fruits, legumes, and whole grains. They are food for the good bacteria in your gut, which turn prebiotic fibre into a short-chain fatty acid called butyrate. Eating prebiotic foods or supplements can help promote helpful bacteria in your gut, boost your immune system, and maintain a healthy digestive system. Prebiotics may also help with the absorption of calcium, which is critical to bone health. Examples of prebiotic foods include garlic, chicory root, onions, apples, and yoghurt.

What You'll Learn
Prebiotics promote healthy gut bacteria
Prebiotics are types of fiber found in vegetables, fruits, legumes, and whole grains. They are food for the good bacteria in your gut, known as probiotics. Prebiotics promote healthy gut bacteria by helping them grow and thrive. Probiotics, or good bacteria, are live organisms that provide numerous health benefits to the gut. However, they need prebiotics to survive and function properly.
Prebiotics occur naturally in many high-fiber foods but are sometimes added to processed foods or available as dietary supplements. Examples of foods that contain prebiotics include garlic, chicory root, onions, apples, dandelion greens, and beans. Eating a varied diet that includes these prebiotic-rich foods can help promote a healthy balance of gut bacteria.
The human gut contains up to 1,000 different types of bacteria, some of which are beneficial, while others are not. Prebiotics help fuel the growth of good bacteria, which can improve digestion, boost the immune system, and support the absorption of nutrients. Additionally, prebiotics can help maintain a healthy weight by making you feel full for longer after meals and regulating metabolism.
While prebiotics have many potential benefits, it is important to note that some people, especially those with gastrointestinal issues like IBS, may experience increased gas, bloating, or abdominal pain when they consume large amounts of prebiotics. Therefore, it is recommended to start with small amounts of prebiotics and gradually increase intake over time.
In conclusion, prebiotics promote healthy gut bacteria by serving as food for probiotics, allowing them to grow and function effectively. By consuming prebiotic-rich foods or supplements, you can support the growth of good bacteria in your gut, which has numerous health benefits for the body.

They can be found in fruits and vegetables
Prebiotics are types of fibre that feed the good bacteria in your gut, leading to several health benefits. They occur naturally in many foods, including fruits and vegetables.
Fruits and vegetables that contain prebiotics include bananas, apples, garlic, onions, and asparagus. Bananas, for example, contain vitamins, minerals, and fibre, including small amounts of inulin, a prebiotic that can help increase healthy bacteria in your gut. Apples are another example of a fruit that contains prebiotics. The fibre in apples includes pectin, a type of soluble fibre that increases good bacteria in the gut and decreases harmful bacteria.
Garlic is another source of prebiotics, specifically inulin and fructooligosaccharides (FOS), which support the growth of good bacteria in the gut. Onions also contain inulin and FOS, which can strengthen gut health and support the immune system.
Asparagus is another vegetable that is a great source of prebiotics. In addition to eating these foods raw, they can be added to cooked dishes like soups, stews, and main courses, or oven-roasted to make them less bitter.
By incorporating these prebiotic-rich fruits and vegetables into your diet, you can promote a healthy gut and potentially reap other benefits that come from having a balanced gut microbiome.

Prebiotics are food for probiotics
Prebiotics are a type of fibre found in vegetables, fruits, legumes, and whole grains. They are also available as dietary supplements. Prebiotics are food for probiotics, allowing them to function properly and effectively. Probiotics are live bacteria in certain foods or supplements that provide numerous health benefits to the gut when consumed.
Probiotics contain a type of sugar called oligosaccharides, which, once digested by gut bacteria, release short-chain fatty acids. These fatty acids are believed to provide relief to people with chronic digestive illnesses and diseases such as Crohn's disease, ulcerative colitis, and irritable bowel syndrome. Probiotics may also help with weight loss and provide benefits against a range of health conditions, including allergies, arthritis, asthma, cancer, depression, and heart disease.
Prebiotics occur naturally in many high-fibre foods but are sometimes added to processed foods. Examples of prebiotic-rich foods include garlic, chicory root, onions, apples, dandelion greens, and yoghurt. Eating 3 to 5 grams of prebiotics per day can benefit gut health.
The human body contains an estimated 100 trillion microorganisms and around 1,000 different species, collectively referred to as the gut flora or gut microbiota. Maintaining a balance between good and bad bacteria is key, and eating foods with prebiotics and probiotics is one way to achieve this. Prebiotics help probiotics grow and thrive, and the two are dependent on each other.

Prebiotics may help with calcium absorption
Prebiotics are types of fibre found in vegetables, fruits, and legumes. They are important for maintaining healthy gut bacteria, collectively referred to as the gut flora or gut microbiota. Prebiotics are indigestible complex carbohydrates that serve as "food" for probiotics, allowing them to function properly and effectively.
Probiotics are beneficial bacteria that promote good bacteria in your digestive tract. Probiotics are live bacteria in certain foods or supplements that can provide numerous health benefits to the gut when consumed. Examples of foods that contain probiotics include fermented foods like yogurt, kefir, and sauerkraut.
When you combine a calcium-rich probiotic food like yogurt or kefir with a prebiotic, it can help increase your body's ability to absorb calcium. This is because prebiotics influence intestinal morphology and the presence of calcium transport proteins. Prebiotic consumption increases cell density, intestinal crypt depth, and blood flow in the lower gut, providing a greater surface area for calcium absorption.
Additionally, prebiotics such as FOS and inulin promote the growth of beneficial bacteria in the colon, which produces Short-Chain Fatty Acids (SCFAs) like butyrate. SCFAs enhance water, sodium, and electrolyte absorption from the gut and may help with diarrhea. Studies show that prebiotics, specifically FOS, may also act as calcium absorption boosters.
In summary, prebiotics may help with calcium absorption by increasing the presence of calcium transport proteins and providing a greater surface area for absorption in the intestine. Additionally, the beneficial bacteria promoted by prebiotics produce SCFAs, which further enhance absorption processes in the gut and may directly influence calcium absorption through gene expression.

Prebiotics can be added to tea
Prebiotics are types of fibre found in vegetables, fruits, and legumes. They are food for the good bacteria in your gut, helping them function properly and effectively. Prebiotics can be added to tea, either by consuming tea blends that contain prebiotics or by adding prebiotic foods to your tea.
Chicory root, for example, has a coffee-like flavour and is an excellent source of prebiotics and antioxidants. You can make chicory root tea by infusing the root in hot water, or you can add it to other tea blends. Similarly, dandelion greens are high in prebiotic fibre and can be used to make tea.
Fruits such as apples are also a good source of prebiotics. You can try adding apple slices to your tea or using apple juice as a base for your tea. Another option is to add prebiotic-rich vegetables to your tea. Onions, for instance, are rich in prebiotics, antioxidants, and flavonoids. You can add sliced onions to your tea or blend them into a juice to add to your tea.
It is important to note that prebiotics can also be found in many other foods, such as garlic and whole grains. A varied diet can ensure you get enough prebiotics without needing supplements. However, if you are looking for a convenient way to add prebiotics to your diet, tea is a great option. Prebiotic tea blends are available in a variety of flavours, and you can also experiment with adding different prebiotic foods to your tea to find combinations that you enjoy.
